Rod-packing.



gland, when pressed against the packing in the box Will ress in a direction against the edges of the co lapsed or flattened tube l throughout the Whole body of the packing; this pressure against the edges of the tubes tending to make them bulge in the center 4and reassurne to the extent of the pressure, their normal round er tubular form. This causes the body of the packing to expand against the rod With the result that the packing is caused to hug close against the rod and insure a tightjoint. The rubber strip guards against impro er distortion of the packing as a Whole.

Mor iications in detail may be resorted to Without departing from the spirit of the invention or sacrificing any For instance, the body portion may be coinposedo'l a plurality of tubular members inl stead of a single tube folded upon itself.

TNhat is claimed as new is;-

1. A rod packing an essential element of which is a body portion composed of a flattened tubular part folded upon itself to bring its adjacent sides into Contact with each other.

2. A rod packing having a body portion of a attened and folded braided tube with its adjacent faces brought into contact with of its advantages. l

each other arranged with its edges to receive the pressure to bulge the tube.

3. A rod acking having a body of a flattened and liblded tube with a plurality of folds one upon the other, a strip of rubber bearing agalnst one face of the same, and .a covering therefor.

4. A rod packing composed of a body portion of a flattened tubular member having a plurality of folds one upon the other, a comparatively rigid member, and a covering secured to the same.

5. A rod packing com osed of a Itubular member attenedand-fo dednpon itself, a rubber strip bearing a ai'nst one face of the same, and a covering, t 1e rubber arranged to be'outermost in use and the flattened tubular body to innermost to receive the pressure and tenti to be bulged thereby.

In Witness whereof, I have hereunto set my hand this 19th day of August, 1907, in the presenre of tvvo subscribing Witnesses.
